Rotator cuff tears can be healed with Prolotherapy about 90% of the time in selective cases. If you have a complete rupture of the rotator cuff, with retraction of the tendon, Prolotherapy will not help you. Also, if you have a large spur digging into the tendon, that needs to be shaved down before Prolotherapy is performed. A number of different people develop rotator cuff tears, but especially for those that work in the trades, people who lift weights, and people who engage in racquet sports, Prolotherapy has been effective. If it is suspected that a spur is digging into the rotator cuff, this can be detected with a simple x-ray. If you have to rule out a complete tear of the rotator cuff with retraction, an MRI is necessary.
